To all whom itmay concern:

Be it known that I, Jon-N lVv MILLER, citizen of the United;- States,residing; at Cleveland,- in the county oit 'Cuyahogm and State of Ohio, have invented certain new and useful Improvementsin @harge-Forming Devices for InternahGombustion Engines, of which the following-is a specifica tion.

This invention 1 relates to charge forming. devices for internal combustion engines, and: comprises 'means for' moi-steningaand heating. the air supply tosuch engines, the object being to increase the. power? of the engine.

A further object of the invention is to provide improved; meansfor introducing a vapor into'the engine which willaprevent or remove carbon deposits.

The device includes-'means' controlling the temperature at which thezmoistened air is delivered to the mixture, the vaporbcing produced by air admit-ted throu'gh'h otand cold air pipes, and superheated in thepipe leading to the intake-pipe't'o the engine.

The invention is illustratedin the accompanying drawing which isa -side elevation, partly in section, of theapparat'us;

Referring specifically to the drawing, 6 indicates an engine and 7' the-intake pipe thereto'from the carburetor 8; A=tank 9, for water, is placedclose-lybeside" the -engine, so as tobewithinthe'infiuence-ot'the heat thereof. This tank-ispartly-filledwith water, to which mayb'eadded asdecarbonizing compound if desired: 'Eittendingfdownwardly from the topofthe'tank is ,a. hot air inlet pipe 10, the lower'end of Which-dips below the surfaceof the liquid.- The hot air is drawn into thetank from-a position adjacent the sidewall and 0XlHLllSt plp0-0f the engine. To equalizeor regulate thetemperature, and prevent excessiveheating. the front end of the tank is prov-ided withacold air inlet pipe 12 which hasahell mouth- 13 just behind the fan, and cold air "is forced bythe fanthrough the pipeand up through the liquid in the tank. The pipe l2has a regulating valve 14. 15 is'a drain cock to draw off the liquid fromth'e tank.

The air bubbling through the water in the tank ismoistened or formsa vapor in the upper part of the tank, from which it is drawnby means of pipe'16 which dips into the tank and is connectedtothe intake pipe 7. A valve 17 controls the amount of flow inthe pipe passes into this heater and is vaporized and drawn thence into and through the pipe.

To prevent the liquid entering the pipe 16, incident tosplashin'g of the water, the mouth of said pipe is provided with a float or checkvalveQO, which, it the water strikes the same,'\vill liftand close the mouth of the pipe 16.

- In operation, the suction of the engine draws in air thronghthe hotair pipe 10, as

wellasthrough the cold air pipe 12, the

action of the latter being assisted by the fan, and the-air bubbles up through the water or other compound, forming a moist vapor which is drawn in through the pipe 16 where it-is'heated and passes to the intake pipe 7 of the engine, where it mixes with the gas,-and forms a mixture which increases the efiieiency of the engine, and which-mayalso serve to prevent carbon deposits. Thetempera-ture and'ainount of the vapor added to the mixture may be controlled by the regulating valves indicated.

What] claim is;

1. The combination of an internal combustion engineand a 1 an driven thereby, of a water tank located beside the engine and adapted to be heated thereby, an air pipe opening into said tank below the water level therein and having its mouth arranged to receive air from the fan, and a vapor tank to said intake ipe, and a float valve a pipe connecting the tank and the intake pipe in the tank, controlhng the mouth of said of the engine. 7 connecting pipe, to prevent entry of liquid 2.
